ABSTRACT
This study examines the effect of different glyphosate doses on the soil texture in four rural communes of the N'Zérékoré prefecture in Guinea. A complete randomized block design was used to assess the impact of glyphosate doses on several soil parameters, including granulometry, aggregate stability, bulk density, and porosity. The analysis of variance (ANOVA) revealed that glyphosate doses significantly influence Granulometry A (p = 0.02881) and show a trend toward affecting soil aggregate stability (SI) and overall stability (Sg), although these effects are not significant at the 0.05 threshold. Conversely, glyphosate doses had no significant effect on Granulometry Lf, Granulometry Lg, bulk density, and soil porosity, as these parameters were more influenced by soil type and year. These results suggest that higher doses of glyphosate can alter soil structure, but the effect varies depending on specific environmental conditions, particularly soil type and annual variations. Careful management of glyphosate doses is therefore recommended to preserve soil quality and support sustainable agricultural practices.
